Crisps are already a giant lump of carbohydrates, but I wasn't arguing they were healthier, I was saying that making a entire healthy meal in a supermarket cheaper than a packet of crisps is not realistic.

If you were making a statement on poverty, I agree with you. Too many people are poor.

I was joking about the bloody crisps, of course :) That being said, many studies link obesity and income inequality: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1733121/
